CONTAINER.

Elmer D. Abramson, Clayton, Mo., assignor to Central States Paper & BagCompany, St. Louis, Mo., a corporation of Missouri Application October14, 1939,8erialNo. 299,407 1 Claim. (Cl. 229-55) This invention relatesgenerally to containers and, more particularly, to a certain new anduseful improvement in containers especially adapted for packing-houseproducts. 1 I

This invention has for its objects the provision of a container for thepurpose stated which is in the form of a flexible paper bag of simpleand durable structure. which is inexpensive and may be readily andeconomically manufactured in large quantities, which may be compactlydisposed for shipment, which is substantially leak-proof and resistantto .penetration by blood and other fluids normally associated with rawmeat and other packing-house products, and which is conveniently usableand efficient in the performance of its intended functions.

And with the above and other objects in view, my invention residesin'the novel features of form, construction, arrangement, andcombination of parts presently described and pointed out in the claim,

In the accompanying drawing,

Figure 1 illustrates in perspective a leak-proof bag embodying mypresent invention in course of construction. Figures 2 and 3 arefragmentary sectionalviews of the partially completed bag, taken alongthe lines 2-2 and,3-3, respectively, Figure 1; 1 a

Figure 4 is a fragmentary perspective view of the'bag-bottom' at anintermediate stage of its construction; '7 V Figure 5 is a perspectiveview of the com- Figure 6 is an enlarged longitudinal sectional view ofthe finished bagbottomf taken approxi-- mately along the line i-6,Figure 5. Referring'now in more detail and by reference characters"tothe drawing, which illustrates 40 includes aninner-member or liner Aconstructed preferably of oil-treated paper on other suitablefluid-proof flexible material and initially of'oblong-rectangularconfiguration, overlapped along its longitudinal margins, which aresecured flatwisetogether by an intermediate layer of water proof orwater-resistant adhesive i extending in a relatively thin somewhatirregular line, as at a, over the outer face f andoutwardly beyond theexposed longitudinal margin lrof the liner A.

Dispo sed in snug-fitting facewise overlying relationship upon andaround the. outer face I of the liner A," is an outer member or jacket Bsecuredin dgewise abutting engagement along its inner longitudinalmarginc with the outer 'tends flatwise over the lineof abutme tween themargins b, c, for a substantial distance, in the provision of anoverlapping section v v e, which is, in turn, secured to the outer face,1

longitudinal margin of the liner A by means of the protruding line a ofthe adhesive l'. 'At'fits otherv longitudinal margin d, the jacket ii ofthe Jacket B by means of a line of waterproof or water-resistantadhesive 2, which extends inwardly beyond the longitudinal margins c ina thin somewhat irregular line as at a, all

in the. provision of a plural-ply open-ended tube 15.

. Along its bottom margin, the tube t is initially closed by suitablyapplying a relatively wide strip-like coating or film of waterproof orwaterresistant adhesive 3 around both the inner and outer faces of theliner A adjacent the bottom margin thereof and pressing the marginalportions of both the liner A and; the jacket B together in the formationof an initial bottom seam I, as shown in Figure 3; As this initial bot.tom seam 4 is formed, the opposed sides of the co-operatively associatedjacket-B and liner A are preferably folded inwardly in' any conventionalmanner in the formation of bellows-type expanding side walls 5'. Itwill, of course, be unders'tood in this connection that any otherconventional type of bag side wall formation may be employed.

Thereupon, a second relatively wide coating or filmof waterproof orwater-resistant adhesive i is applied around both sides of the outerface v of the initial seam I and the latter. folded up first to theposition shown in Figure 3 and then again folded or rolled to theposition shown in Figure 4 and pressed flat in the,provision of adouble-rolled seam having a layer or film of adhesive between eachitnerface of the bag-form ing materials, as shown in Figure 6.

In use, the raw meat portions, such as livers,

hearts, kidneys, bone tips, rib tips, melts, sweetbreads, and the likeare placed in the bag and Y the top rolled down and closed with a heavyrub-- her band or staple, or simply gathered and twist- "ed, as the casemaybe. It is usually customary,

of course, to put difierent portionsv in'separate bags for facilehandling in the meat coolers. In I any case, the bloodand other liquidswhich ordinarily exude from the meat will be securely retainedin the bagand will not readily attack the adhesive of the seams for eifectingdisintegration and rupturing of the bag bottom, and, finally,

" by reason of the fact that the liner A'is made of oil-treated paper,the blood and meat juices will not penetrate through the side walls ofthe bag.

Thus it will be evident that, by my present invention, I provide a bagwhich is rugged, durable, and entirely leak-proof, and which is ofsimple and economical construction that it may be very readily andeasily manufactured. The bags of my present invention are further fiatand compact and may be readily shipped from the point of manufacture tothe packing houses without appreciable freight or other handlingcharges.

It should be understood that changes and modifications in the form,construction, arrangement, and combination of the several parts of thebag may be made and substituted for those herein shown and describedwithout departing from the nature and principle of myinvention'.

Having thus described my invention, what I claim and desire to secure byLetters Patent is,

An open-mouthed pinch-bottom bellows type bag having an inner moistureresistant liner jacket and an outer covering jacket telescopicallyinterfitted and secured together in the formation of a plural-plyopen-ended tube, said tube being provided with diametrically opposedlongitudinally extending inward folds of substantially V- shapedcross-section dividing the tube into Opposed face walls connected byextending side bellows, said tube being provided along its bottom marginwith a wide strip-like coating of waterresistant adhesive around boththe inner and outer faces of the liner jacket and said side walls andsaid bellows being pinched together at said bottom end of the tube andbeing thus adhesively sealed in the formation of an initial transverselyextending water-tight end-closure, said end-closure being furtherprovided upon its external faces with a relatively narrower coating bandof ELMER D.
